Document Type and Number:
Japanese Patent JP2588594
Kind Code:
B2
Abstract:
A horizontal deflection circuit comprising a horizontal output transistor, and a drive circuit is connected between the base and the emitter of the horizontal output transistor to supply a base drive voltage to the horizontal output transistor in order to control the conduction between the collector and the emitter of the horizonal output transistor, wherein first and second switching means are provided in parallel between the base of the horizontal output transistor and the drive circuit (or between the emitter of the horizontal output transistor and the drive circuit), the first switching means permitting only the current to flow from the base of the horizontal output transistor to the drive circuit (or from the drive circuit to the emitter of the horizontal outut transistor) and the second switching means being conductive only during the conductive period of the horizontal output transistor.
